Psychiatric History of Presenting Illness Mnemonic

Abdulsamad A. Aljeshi, MBBS, FRCPC

Published: July 18, 2024


To the Editor: It is essential for individuals in the medical and psychiatric fields to be skilled in obtaining a psychiatric history. During my training at the University of Toronto, my preceptor, Dr Gerald Shugar, introduced the 6 Ss: Start, Setting, Stressors, Symptoms, Sequelae, and Supports.

Over the years, I have adopted and modified the 6 Ss to develop a mnemonic that has evolved into its current version, which is still used by my trainees and referring physicians from other specialties. To aid in taking a comprehensive psychiatric history of presenting illness (HPI), I developed the following mnemonic device: the “Psychiatric HPI 9 Ss.” Each letter represents an essential part of the psychiatric HPI, as follows:

  1. Start
  2. State: circumstances of the event
  3. Stressors: bio-psycho-social
  4. Symptoms: bio-psycho-social
  5. Psychosis
  6. Suicide
  7. Substance: prescribed and illegal
  8. State of function: current
  9. Systems review: other psychiatric diagnoses

The 9 Ss are easily remembered and can be utilized by students, residents, psychiatrists, and other clinicians to facilitate the organized collection of relevant information when obtaining the psychiatric HPI.
